8. Start the engine and run it at a speed
slightly above low idling. Raise the water
temperature to at least 90°C (194°F), and
then run the engine for about 10 minutes
with the thermostat open.
9. Stop the engine, wait until the cooling water
temperature becomes lower, and then
remove the drain plug (4) to drain the water.
10. After draining, clean the cooling system
using a cleaning agent. When using the
cleaning agent, follow the instructions
included with the agent.
11. Repeat the steps 4 to 8 to rinse the
cooling system.
12. Tighten the drain plug (4).
13. Take time and slowly add the new
coolant (mixture of antifreeze and tap
water) to the radiator through the fill port
until it is full.
14. Close the radiator cap (3).
15. Warm up the engine. Use the meters to
check that there are no irregularities in
the cooling system at this time.
16. Increase the water temperature to at
least 90°C (194°F). Then, run the engine
for about 10 minutes with the thermostat
kept open.
17. Stop the engine, wait until the cooling
water temperature becomes lower, and
then check the level of coolant in the
radiator.
If necessary, add cooling water until the
radiator is full.
18. Close the radiator cap (3).
19. Clean the interior of the reserve tank (1),
and then add coolant to the upper limit
(H).
20. When the coolant has been replaced,
inspect the coolant level once again after
operating the machine.
Once the machine is operated, the
coolant is distributed throughout the
entire system, resulting in the lower
coolant level.
Replenish the cooling water that has
been used.
